Public procurement assumes series of procedures by which authorized contracting clients obtain services, works and welfare. They must therefore take care of being cost-effective, i.e. taking into account price, quality, functionality, accessibility and social and environmental aspects. Sustainable public procurement has developed by introducing elements of sustainable development into public procurement procedures. It implies generating benefits not only for economies and organizations but also for society by reducing environmental damage. In order to successfully implement sustainable public procurement, it is essential to focus on the implementation of sustainable policies at the local and national level with the support of legal instruments. To improve social equity, environmental sustainability and economic progress, focus needs to be shifted from savings and increasing profits to sustainability issues and sustainable business. Since tourism is the most vital and vibrant sector of the economy in the Republic of Croatia, and has a significant potential for further growth, although its development, in addition to its many positive effects, unfortunately has a negative impact on the environment. It is very important to turn to a "green" economy, which implies "greener" tourism. The goals of turning to environmentally friendly tourism are preserving the environment and attracting new eco-conscious tourists, thus resulting in a direct increase in trade, which implies profit. Such a viable tourist destination becomes a promising investment opportunity, permitting opportunities for job creation and a generally positive climate for the local community.
